Spherical Object Drops from the Sky in Namibia

Officials from Namibia have been examining a hollow ball that fell from the sky back in November 2011. So far, they haven’t had much luck identifying it, so have called in NASA and ESA, hoping the space agencies can provide some answers. The spherical object has a circumference of 1.1 meters (43 inches) and was found in a remote area in the northern part of the country, about 750 kilometers (480 miles) from the capital Windhoek, according to police forensics director Paul Ludik, quoted in an article by AFP.

Ludik described it as made of a “metal alloy known to man” (so cross alien spacecraft part off the list), weighing six kilograms (13 pounds).

This isn’t the first time balls from space have dropped in on unsuspecting countries.

Space spheres found in Australia and Brazil in 2008.

Back in 2008 spherical objects fell to Brazil and Australia, and there have been previous reports of similar objects, as well.

After some post-crash forensics, the two objects in 2008 were identified the as a Composite Overwrapped Pressure Vessel (or COPV), which were carried on the space shuttles, and are a high pressure container for inert gases. COPVs have been used for a variety of space missions.

They are built with a carbon fiber or Kevlar overcoat to provide reinforcement against the vast pressure gradient between the inside and outside of the container, and so can survive re-entry through Earth’s atmosphere.

The one in Namibia was found 18 meters from its landing spot – it created a mini-crater 33 centimeters deep and 3.8 meters wide.

Other suggestions of what the object could be is a piece from a space gyroscope, a satellite part, a tank from one of the Apollo missions, or a part of a Russian spacecraft, (which have been known to crash to the ground, as well)

    Likely a hyroscope..

      Is that what you get when a horoscope and a gyroscope inter-breed?

    Could it be the Mythbusters cannonball?

      I remember something from comedy central recently, “…but, they were able to bust the myth about cities being safe from cannon fire” ha ha

    “Ludik described it as made of a “metal alloy known to man” (so cross alien spacecraft part off the list)”

    Fallacy. Just because something is made of material known to man, it doesn’t necessarily have to be “man-made”. This then implies that all alien spacecraft parts are made of materials that are unknown to us.

    Not that I believe its alien-ware haha

      I would say yes and no. It is a philosophical fallacy, but an empirical non-fallacy. The likelihood for “alien spacecraft” was minute, but the presence of our own alloys tests the parsimonious explanation.

      They’re just using known alloys to fool us. Those aliens are cunning. Very cunning…

      Re the “metal alloy known to man” quote…

      Most ‘alien spacecraft’ debris is described as being ‘unknown to science’ or something like that, before being whisked away by a hitherto unknown department of the military: this quote is a clear parody of that. This is a big, chunky bit of metal with a large weld around the equator. If you are launching to travel to the stars then every gram would be critical: if you are launching something from Earth to LEO then you might well settle for a cruder and heavier construction that you trust. It may be space technology, but it is not from outer space.

      That being said, it is interesting to speculate what future spacecraft bits might look like. Future civilizations will still have the same periodic table of the elements to play with, and it is increasingly unlikely that there are no magic combinations of elements that have vastly superior properties. The main gains will probably come from making large components with fault-free microstructures that can approach the theoretical strength of the bonds. The COPVs are a better solution, because they use carbon-carbon bonds which are stronger for the same weight. The ideal solution might be a graphite sphere, or a woven buckytube mesh, perhaps with chromium plating to stop diffusion of low Z gases. That would be using an element that was clearly ‘known to man’ but in a way that we cannot currently match.

      In fact, the sad truth is probably that any such part of an alien spacecraft will be lighter and less dense, and so would probably not survive re-entry unless it was specifically designed to do so.

      Well, technically it is from an alien spacecraft. Unless Namibia has a space program they haven’t told us about.

    Is it too small to have been a dummy mass? I think some of those are still floating around up there, though that new image does bear a striking resemblance to those pressure vessels

    Looks like a toilet-tank float to me.

  • Anonymous December 23, 2011, 4:26 PM

    That pressure tank must be pretty tough to thump out a crater 33cm (about a foot) deep and 3.8 meters wide without crumpling.

    It’s Ivanman, the spellchecking terminator, he fell from a tree, at large.

    I find it odd that the thought of analyzing the interior for a residual of what it was designed to contain hasn’t been broached.
